A method of producing an essentially radial annular collar on the hollow annular end part (15) of a component (7), said method comprising a deformation step so as to obtain a collar preform (23) having a radial part (23b) and a step of spreading said preform (23) so as to obtain, by pressing, the final forming of the collar; in which, during the deformation, an intermediate portion (23e) of the free lateral surface of the radial part (23b) is inclined by a non-zero angle beta with respect to the perpendicular to the axis (5) and, during the spreading, at least an end area of said intermediate portion (23e) is inclined by an angle delta with respect to the perpendicular to the axis (5), the angle delta being strictly greater than the angle beta. The invention also concerns a method of holding a bearing (1) on a shaft (7), and an assembly comprising a bearing (1) and a shaft (7).
